When it comes to grinding equipment, many people will think of Raymond mill and ball mill, thinking that they are all grinding equipment, and it doesn't make a difference.
Actually, although these two types of equipment belong to grinding mill, there are still differences in their grinding operations. Users should be differentiated when choosing, and understand the difference between them, and choose what kind of grinding mill we need.
The difference between Raymond mill and ball mill includes the following aspects:
Raymond mill belongs to vertical structure and is a superfine grinding equipment. The grinding fineness of Raymond mill is below 425 meshes. Ball mill belongs to horizontal structure, whose area is larger than that of the Raymond mill. The ball mill can grind the materials with dry or wet method, and the fineness of its finished product can reach 425 meshes. It is a common equipment for grinding materials in mine industry.
2. Different applicable materials
Raymond mill adopts grinding roller and grinding ring for grinding, which is suitable for processing non-metallic minerals with Mohs hardness below level 7, such as gypsum, limestone, calcite, talc, kaolin, coal, etc. While ball mill is usually for grinding high hardness materials like metal ore and cement clinker. Generally, Raymond mill includes European grinding mill, overpressure trapezoidal grinding mills, and smart European grinding mills. And ball mill are generally divided into ceramic ball mill and steel ball mill according to different grinding materials.
3. Different capacity
Generally, ball mill has a larger output than Raymond mill. But the corresponding power consumption is also higher. During the process of production, ball mill has many disadvantages like big noise and high dust content. Therefore, it's not suitable for environmentally friendly processing. The traditional Raymond mills are insufficient in terms of production capacity, but the new types Raymond mill, such as SBM's MTW European grinding mill and MTM Raymond mill, have made great breakthroughs in production capacity and can meet the production demand of 1,000 tons per day.
4. Different investment costs
In terms of price, ball mill are cheaper than Raymond mill. But in terms of overall cost, the ball mill is higher than the Raymond mill.
5. Different environmental performance
As we all know, the powder industry has particularly strict requirements for environmental protection, which is the main reason why many powder manufacturers have successively rectified. Raymond mill adopts a negative pressure system for dust control, which can control the discharge of dust, making the production process clean and environmentally friendly. While the area of ball mill is larger, so the whole control is difficult, and the dust pollution is larger than that of Raymond mill.
6. Different quality of finished products
Both Raymond mill and ball mill adopt grinding method. But the ball mill uses sphere to collide with the mill cylinder, the contact surface is small, and the finished powder is not as stable and uniform as Raymond mill.
In conclude, the performance of two equipment has been explained. In fact, the biggest difference between the use of Raymond mill and ball mill is that the area of the ball mill is larger than that of Raymond mill, and the price will be more expensive! As for which is better? It still depends on the material you want to process before you can make a judgment as to which one is right for you.
